Alongside the Peškera bay, northeast of the heart of the old city, there is North Defence Tower. It was built in the 15th century. Today the edge is still partly preserved.
Between the three towers, as well as around the peninsula, there used to be the City’s ramparts. Parts of it are still best visible from the board-walk along the northern side of the City. The City was detached from the mainland by a trench.
